The core feature is a recursive DAG-style component graph (“Kanji Atlas”) that breaks kanji down layer by layer into radicals and graphemes, so you can visually explore how characters are constructed and related to one another.

“What exactly constitutes "external geometry" in BEM methodology? I'm learning BEM methodology and encountered this principle in the documentation: "The block shouldn't influence its environment, meaning you shouldn't set the external geometry (margin) or positioning for the block." I need clarification on what CSS properties are definitively considered "external geometry" and how to handle practical layout concerns. Specific Questions 1.
